Further increase in avalanche danger as a consequence of new snow and wind. It is inadvisable to engage in backcountry touring in steep terrain.

Heavy snowfall to above 900 m. The wind will be strong in the vicinity of peaks. In the late morning danger level 4 (high) will be reached at intermediate and high altitudes. In the typical avalanche paths the avalanches can reach fairly large size and in some places endanger transportation routes situated at relatively high altitudes. In particular in the vicinity of peaks and on steep slopes medium-sized and, in many cases, large slab avalanches are possible as a consequence of the northeasterly wind,, also in gullies and bowls, and behind abrupt changes in the terrain. Additionally avalanches can also be released in the old snowpack and reach large size. Whumpfing sounds and shooting cracks when stepping on the snowpack are a clear indication. Avalanches can be released, even by a single winter sport participant. Remotely triggered and natural avalanches are probable. The avalanche prone locations are prevalent and are barely recognisable because of the poor visibility. The conditions are dangerous for backcountry touring outside marked and open pistes. The current avalanche situation calls for extensive experience in the assessment of avalanche danger and careful route selection.

20 to 30 cm of snow, and up to 40 cm in some localities, has fallen since Friday above approximately 1200 m. 30 to 50 cm of snow, and up to 60 cm in some localities, will fall on Sunday above approximately 1000 m. As a consequence of new snow and a moderate to strong wind, sometimes large wind slabs formed since Friday in gullies and bowls and behind abrupt changes in the terrain as well as above the tree line. The wind slabs of last week are covered with new snow and therefore difficult to recognise. The new snow is lying on the unfavourable surface of an old snowpack in particular on shady slopes. Especially at high altitudes and in high Alpine regions snow depths vary greatly, depending on the infuence of the wind.

Monday: Snowfall to low altitudes. Further increase in avalanche danger in the course of the day. From starting zones at higher altitudes large natural avalanches, capable of reaching a long way in some cases, must be expected. It is inadvisable to engage in ski touring, freeriding and snowshoe hiking outside marked and open pistes.
